SAMUEL .LQ HALL, OF CHICAGO, ILLINQIS.

BAKERS OVEN.

SPECIFICATION Forming part of Letters Patent No. 322,282, dated July 14, 1885. Application filed October 18, 1884. `(No model.)

To all whom t may concern:

Be it known that I, SAMUEL L. HALL, of Chicago, in the' county of Cook and State of Illinois, have invented a certain new and useful Improvement in Bake-Ovens, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in Which- Figurel is a front view of my improved oven with parts of the wall broken away. Fig. 2 is an enlarged detail section taken on line 2 2, Fig. 1. Fig. 3 is a horizontal section taken on line 8 3, Fig. 1; and Fig. 4 is an enlarged detail section taken on line 4 4, Fig. l.

My invention is an improvement in the construction of bake-ovens; and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, A represents the body of the furnace, B, the uptake or chimney, C, the fire-box, located in one of the walls of the furnace, D,the chute through which fuel is passed to the fire-box; E, asliding door to the chute, which may be .held vopen by a weight, F, and rope orY cord G, passing over pulleys H, (see Fig. 1;) I, sifting-box; J, ashpit; K, grate-bars between the box and pit; L, the doors to the box and pit; M, the bakin g-oven, and N the door to the oven-chamber, held open, if desired, by a weight, O, rope or cord I), and pulleys @mover which the rope or cord passes. mentioned are of common and well-known construction, and I make no claim thereto; nor do they need any further description in this specification.

In this oven the furnace, uptake or chimney, fines, and openings are all located in the front wall, with the exception of the flue which connects the rear part of the oven with the uptake, the furnace being located at one corner, while the uptake or ehimneyis located at the other corner.

When the fire is first started, the products of combustion pass from the fire-box directly into and across the front of the oven and up a short vertical ilue, R, to the main uptake, as indicated by dotted arrows in Fig. 3. Vhen the fire is fully started and burning well, the ilue R is closed by a damper, S, and the pro- All of these features thus far l ducts of combustion made vto pass through the baking-oven, as indicated by full arrows, Fig. 3, to the back part, where they enter a horizontal flue, T, preferably in one of the side walls of the furnace, that transfers them to the front wall into the vertical continuation T of the main uptake. The fines It and T are sep-A arated at the lower end of the uptake by apartition, U. (See Fig. l.) The flue T is corr trolled by a damper, T.

Air is admitted beneath the re-pot through a horizontal flue, V, alongside the sifting-box, and provided witha damper, V. (See` Figs. 1 and 4.) The front end of this ilueVis conextending upwardly therefrom, horizontally in cl ose proximity to and over the oven-door, and obliquel y into the'uptake, and provided with dampers W and VW, and communicating with X, just over the oven-door N. (See Fig. 1.) This flue XV may be termed a dust-flue, for, by closing the dainpers S, T", and V, and opening those W W2, all the dust, when the grates are shaken, will be drawn out by the draft through this flue to the uptake without going into the bakingchamber. The dust passes through the iiueV to the flue W. By closing the dampers S, T", and W, and opening that W2, foul gases frolnthe baking-chamber will be nected with theuptake by means of a flue, W,

the baking-chamber by means of an opening,

taken out through the opening X, flue W, and

the uptake.

Yrepresents apeep-hole in the front or other wall of the oven, provided with a door, Y. (See Fig. 3.)

I claim as my inventioni 1. A bake-oven provided with a front wall formed with a furnace at one corner, an uptake at the opposite corner, partition U in the fine, horizontally over the oven-door, and upa dust-ilue extending upwardly from the airuptake, formingvertical continuation T, and A,

wardly into the uptake over the direct flue,

and dampers for controlling the `lines and continuation, substantially as set forth.

2. A bake-oven provided with a front wall formed with a furnace at one corner, an uptake at the opposite corner, dustflue, airilue,

direct ilue, continuation, openings, doors, and

danipers, all located therein, and a side Wall having a single indirect liuc extending from the rear of the oven-chamber to the continnation, substantially as set forth.

3. A bake-oven provided with a front Wall formed with a furnace at one corner, an uptake at the other corner, a dust-f1ue, W, eX- tending across the wall from the furnace to the uptake,'and having an opening, X, into the oven-chamber, and dampcrs to control the ilue, substantially as set forth.

4C. A bake-oven provided with a front Wall formed With a furnace at one corner, an uptake at the other corner, an air-flue alongside the sifting-box, a dust-flue, W, extending up- Wardly from the ainflue, horizontally over the oven-door, and upwardly to the uptake, and dampers to control the dust'flue and air-flue, substantially as set forth.
